Steyliff Grove is one of the dungeons in the game Final Fantasy XV.
A Menace Sleeps In Steyliff[]

The broken wall that leads to the sealed door.
Starting in Chapter 15, the player has the opportunity to delve deeper into the main-game dungeons. To complete the A Menace Sleeps In Steyliff quest (as a part of the larger Menace Beneath Lucis quest line), the player must journey to Steyliff Grove. The Menace Dungeon entrance lies beyond the great hall at the bottom of Steyliff where the Quetzalcoatl spawns during the regular dungeon. There is a hole broken into the left side of the back wall that leads to the sealed door. There are 100 floors overall.
A word of caution to the dungeon delver that bears repeating - there is no ability to save while occupying any area of the game considered a dungeon, outside of Auto-Saves (which will activate at certain checkpoints, such as camping). Completing Menace Dungeons can take a considerably longer amount of time than is demanded of their normal dungeon counterparts, and Steyliff's is the deepest of the Menace Dungeons. It is advised to plan accordingly before beginning the journey.
Upon approaching the sealed door, one of two dialogues will play. If this is the player's first Menace Dungeon:
Prompto - This door here. Is it one of the seals?
Ignis - It seems highly likely.
Gladiolus - Well, we got the key. Do we use it?
Noctis can then use the Sealbreaker's Key on the lock. The large seal has a series of spinning parts that light up red Solheim-esque symbols before swinging inward.
Gladiolus - Hey, now! Finally making some headway.
Ignis - At last, we have broken the seal.
Prompto - Yeah, I don't think that means what you think it means.
Noctis - Means we have to go.
Prompto - I know that. Oh, in there?
If this is not the player's first Menace Dungeon, upon approaching the door:
Gladiolus - Another door. Who wants to see what's behind? I'm game if you are.
And after opening the door:
Prompto - Hey, it's open!
Noctis - Let's hit it!
The first of many sets of stairs awaits.

On Floor 10, there is the opportunity to camp at Intellune Haven and collect a Hi-Elixir. The Royal Edition DLC adds the monoliths feature to the Menace Dungeons. Monoliths are small stone monuments upon which are carved the various stories behind the sealing of the dungeons. They are written in the form of poems, carved in white on a black stone slab, and are likely written by several authors (though the monoliths in Steyliff are undoubtedly written by the Oracle King). Each monolith is headed by the phrase "Whence comes the Night, let shine the Light." In this room waits the first of the nine Steyliff monoliths, and it reads:
O she so wise will take her shining trident in her hand
Then she shall rise to spread the word of peace across the land
And lest the world forget her efforts or the life she gave
Upon these monoliths her noble deeds I shall engrave
Incidental dialogue will activate after reading the poem for the first time:
Noctis - "Whence comes the Night, let shine the Light"...
Prompto - Translation?
Gladiolus - Pretty sure it's saying, "find the big, bad monster and take it down."
Ignis - I don't wholly disagree with your interpretation, but it lacks nuance. Perhaps seeking more inscriptions will help elucidate their meaning.

Searing bolts of lightning cracked downward from the skies
Yet 'twere not clouds but wings that soared before my very eyes.
*
Were our foe the Scourge of Stars, it could have been purified
Yet this menace was no daemon—that, we soon descried
The Oracle I loved was slain and with our flags she burned
Beleaguered and bereft, to the forest I returned.

With the rains that fall upon the earth and nurture life
Also come the bolts of lightning, couriers of strife
Though man can't curb the fearsome whims that rule the natural world
Against a beast, the white flag of defeat needn't be unfurled.
*
Looking to the Oracle for guidance in these trials
I realized we might defeat the menace with our wiles
First we draw the devil down and seal it in a cage
Then entrust its exorcism to the coming age
And 'til an heir arises to succeed the life she led
Her staff in hand, I shall become the Oracle in her stead.
